Google has a great trivia game out, Smarty Pins. They present you with a map of the world (usually zoomed in to somewhere in the area of the answer). You are given a trivia question. You answer the question by dropping a pin on the map where you think it should go. The number of miles off you are from the actual location get deducted from your total start milage, (1,000). Answering questions quickly gets you extra miles.
It’s surprisingly fun. However, it’s easy to loose quickly. I was way off in the answer to one question (wrong coast of the US), and that ended my game completely.
